This slide presentation explains the "Data Web" vision, including some of the preliminary standards and technologies. It also covers tools and technological building blocks developed by the AKSW research group from Universitat Leipzig. Note: This is a very comprehensive overview, but lacks exposition. These slides are sufficiently detailed to be valuable as a jumping off point for developing a lesson plan or lecture. For example, many LD tools and applications are mentioned which could be explored further as course assignments.

- Accesses DBPedia's SNORQL/SPARQL endpoint and issues simple queries.
- Knows methods such as Direct Mapping of Relational Data to RDF (2012) for transforming data from the relational model (keys, values, rows, columns, tables) into RDF graphs.
- Knows the "five stars" of Open Data: put data on the Web, preferably in a structured and preferably non-proprietary format, using URIs to name things, and link to other data.
- Understands that Linked Data (2006) extended the notion of a web of documents (the Web) to a notion of a web of finer-grained data (the Linked Data cloud).
- Understands that resources are declared to be members (instances) of classes using the property rdf:type.
- Understands that URIs and literals denote things in the world ("resources") real, imagined, or conceptual.
- Understands that to be "dereferencable", a URI should be usable to retrieve a representation of the resource it identifies.
